Fixing Leggy Seedlings Under Grow Lights

Spindly seedlings = lights on too long. Plants need dark period for respiration. Match light hours to natural daylight + 2 hrs max. Use timer.

Light Schedule

• 14 hrs on / 10 hrs off is standard.
• Don't exceed 16 hrs total.
• Keep lights 2–3" above canopy.

Photosynthesis needs downtime.
